L4938EPD13TR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 26V, but it's recommended to keep it below 20V for optimal performance and to prevent overheating.
  • To ensure stability, use a minimum output capacitance of 10uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, keep the input and output capacitors close to the regulator and use a low-ESR capacitor for the output.
  • The minimum input voltage is 7.5V, but it's recommended to keep it above 8V for optimal performance and to ensure the output voltage is within the specified range.
  • The L4938EPD13TR is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage to prevent overheating and ensure reliability.
  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance and junction temperature to ensure the regulator doesn't overheat.
